Erinna

Erinna was a Corinthian hetaera who was employed by Anthousa during the Peloponnesian War. In 431 BC, she met the mercenary Kassandra, who was sent by Anthousa to help Erinna find the missing hetaera Kleio, whom Erinna believed was kidnapped by pirates. Kassandra followed Erinna to the Lechaion port, and she then spotted the pirate ship in the harbor, battled the ship, boarded it, slew its crew, and confronted Kleio. Anthousa discovered that Kleio had attempted to escape with the help of Amphion, and she brought Kleio back to Erinna against her will, earning her payment.
